Key Features
  • ONLY fully visible splice kit on the market

  • Includes 5 clear shrink tubes + 5 wire crimps 
  • Provides a permanent waterproof electrical seal

Instructions

You'll need a heat source to properly shrink the tubing — a butane torch or lighter works great for this splice kit.

  1. Slide the heat-shrink tubing onto the water pump wires before crimping.
  2. Attach the provided connectors to the wires using a crimping tool.
  3. Center the tubing over the connector and begin heating from the middle outward.
  4. As the tube shrinks, the melted adhesive inside begins to flow and bond the connection.
  5. A permanent watertight seal is formed when the tubing fully conforms to the wire and connector.

Rewiring your submersible well pump? This splice kit makes clean, watertight electrical splices easy for DIYers, well drillers, and pump installers. It’s the only clear splice kit on the market, so you can see every connection as you make it — and catch any future issues fast. The tubing rapidly shrinks around your wire and crimp, forming a permanent, flexible, waterproof barrier that protects deep underground connections for years. 

Well Pump Splice Kit Trusted by Pump Installers

Back40's crystal clear tubing gives pump installers, well servicemen, and DIYers unmatched visibility when connecting the well pump wire. Unlike traditional methods, you can actually see your butt connectors, confirm the quality of the splice, and ensure long-term security for underground systems where water flows and pressure fluctuates — especially in groundwater applications.

Compatible with 14, 12, and 10-gauge well pump wire, this kit also supports efficient cooling by creating a sealed, low-profile connection without bulking up the wire wall.

It's already included with every full RPS pump kit, but if you're buying a motor or pump end separately, this is a must-have accessory for a proper, lasting install.

Water-Tight Seal for Long-Term Protection

This premium kit uses heat-activated tubing and sturdy crimp connectors to create a permanent watertight seal. It’s perfect for submersible deep well installs and other water-tight applications. 

Inside each tube, a special thermoplastic adhesive melts as the tubing rapidly shrinks, locking out moisture and debris for years.

Whether you're redoing a submersible pump install or replacing an old splice, this splice kit makes it easy to confirm wire connections before sealing. It’s a trusted tool for rural farmers who want clean, reliable electrical splices that hold up underground.

Our Pledges to You

  1. Be a company our Grandfathers would have trusted. The trend of ‘outsourcing’ customer support after the sale is a trend we wholeheartedly oppose. We are an American, family run company and our USA engineers support you before and after the sale.
  2. No sales pressure. Ever. Nobody in the company is paid on commission. We think this is important. Their role is to make sure they find the right pump for you and your well. If we don’t have a livestock solar pump that will suit your needs, we will help you find a solution elsewhere. Our job is to help get you water.
  3. Reliable Water. All manufactured products have occasional issues and we can’t claim to be perfect. However, we are proud of a near perfect track record in getting our customers water. This starts with selling a pump sized for your usage with our Water Assurance Plan and promptly addressing warranty issues to get you up and pumping again quickly.
  4. Give you the power! When you control your ability to pump water out of the ground, whether that is in the field or at home, it makes you more resilient and independent. We are here to help educate you about solar water pumping for livestock and our systems over the phone, with our manual - so you can install yourself. Take control of your water supply today.
  5. Fight for the American rancher. RPS is a David & Goliath story of a small American company fighting against a big European pump corporation that cares more about profits then the longevity of their pumps and the sky-high price for ranchers. Thanks to all our customers for the support of small business vs. foreign corporations trying to profit off some of the hardest working people in our great nation.
